HEATER FOR CARS.

SPECIFICATION formingpart of Letters Patent No. 256,006, dated April 4;,1882,

(No model.)

To all whom it may concern:

- Be it known that I, DAVID MARION KIRK- PATRICK, of Kansas City, in thecounty of J ackson and State of Missouri, have invented a new and usefulImprovement in Heaters for Railway-Cars, of which the following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a sectional side elevation of my improvement shown asapplied to a car. Fig. 2 is a sectional end elevation of the same, takenthrough the line w m, Fig. 1. Fig. 3 is a plan view of the top of thecar, showing the bed-plate for the stove and the seat for the cover.Fig. at is a bottom view of the stove andcover. Fig. 51s a cross-sectionof the bed-plate, taken through the line y y, Fig. 3.

The object of this invention is to provide for the heating of carswithout obstructing the seat-space or main floor of the car with theheater.

My invention is especially applicable for use on street-cars, but may beused upon all kinds of passenger cars or vehicles.

A represents the wheels, B the body, and O the roof, of a street-car.The middle part of the roof 0 is cut away, and in the opening thusformed is secured the bed-plate D, that-suppoi ts the heater, and whichis attached at its four corners to the roof 0. The sides and ends of thebed-plate D are recessed, as shown in Fig. 3, to allow the heated air todescend into the car.

E is the stove, which is made with a movable grate, F, to support thefire, and drawer Gr to receive the ashes and allow them to be readilyremoved.

To the center of the stove plate or bottom E is attached, or upon it isformed, aflaringor conical pivot, H, which is made broad to serve as afoot to rest upon the bedplateD and give a firm support to the stove.The pivot has a double incline formed upon its lower surface, as shownin Fig. 4, and rests upon a similarlyformed seat in the center of thebed-plate 1), as shown in Fig. 3.

The pivot H is secured to the bed-plate D by a two-part collar, I, theinner surface of which is made conical to fit upon the pivot H, and thusfasten the stove to the said bed-plate D. The stove E is furthersupported in place by the two studs or pins J, attached one to theforward part and the other to the rear part of the bottom E of the saidstove E, and the lower ends of which rest in grooves K, formed in thebed-plate D. The grooves K are curved upon the arc of a circle havingits center in the axis of the pivot H.

In the bottom of each groove K are formed two inclines, L, leading inthe same direction and meeting-at the central line of the bedplate D, sothat the stove can be turned only in one direction, and in the bottom ofthe said groove, at the inner ends of the inclines, is formed a recess,M, to receive the lower end of a stud, J, to prevent the stove frombeing jarred out of place. This construction also prevents the stovefrom being turned any far ther than to bring it into line with thelength of the car.

The stove E and the opening in the root' -G of the car are covered witha cover, N, which is made with an arched top and flaring sides and ends,and has its lower edge turned outward or flanged to rest upon the roof 0of the car. The cover N is attached to the ends of cross-bars O, whichare attached to the bottom E of the stove E, so that the said coveryvill be carried around with the stove as the said stove is turned uponits pivot. When the stove is in line with the car the flanged lower edgeof the cover N rests upon a rubber packing, 1?, attached to the roof 0to make the joint between the said cover and roof air-tight when thestuds J are resting in the recesses M, and the inclines of the pivot Hare in line with the corresponding inclines of its seat.

In the forward end of the cover N is formed an opening which is closedby a door, Q, and which is made of such a size that fuel can be readilyinserted in the stove and the ash-pan removed through it. e

The forward end of the stove F is provided with a door for the insertionof fuel and a damper for regulating the draft.

The stove E at its rear endis provided with a smoke-pipe, R, whichpasses out through an opening in the rear part of the cover N. The stoveE and cover N can be fastened in place by ahook, S, or other fasteningattached to the root 0 at the edge of the opening through it, and whichengages with one of the cross-bars 0. With this construction the stovecan be turned when the horses are changed from one end of the car to theother to keep the forward end of the stove toward the forward end of thecar, so that the draft will operate properly.

In keepers T, attached to the lower side of the roofO, at the ends ofits opening, are placed aprons U, so that the said aprons can be movedout to fit against the recessed ends of the bedplate I) to prevent coalor other fuel from dropping down into the interior of the car whensupplying the stove with fuel, and to prevent ashes from droppingintothe interior of the car when the ash-drawer is being removed from thesaid stove. WVith this construction the heated air from around the stoveE will pass down into and circulate through the interior of the car,which circulation of heated air will be assisted by the draft caused bythe motion of the car. With this construction, also, should the car bethrown from the track and overturned, the heater will be projected to adistance from the car, and the danger of the car being set on fire fromthe heater will be avoided.

Having thus described my invention, Iclaim as new and desire to securebyLetters Paten t-- 1. The combination, with a car having a coveredrecess or chamber in the roof, of a stove arranged in said chamber, andprovided with a bed-plate recessed at the ends and sides, whereby theheat may be carried from the stove to the inside of the car, asdescribed.

2. A car-stove having the bottom pivot, H, with doubleincline on itslower surface and the studs J J on the front and rear of bottom, incombination with a bed-plate having a seat with a double inclinecorresponding to that of the pivot and the inclined arc grooves L K,

whereby the stove can turn only a half-revolution and always be broughtinto position to suit the direction into which the car is to travel,asdescribed.

3. In a car-heater, the combination, with the apertured roof 0, ofthebed-plate D, havinginclined and recessed grooves K, the stove E, havingconical pivot H and studs J, and the collar I, substantially as hereinshown and described,whereby the stove will be securely supported and canbe readily reversed, as set forth.

4. In a heater for railway-cars, the combination, with the aperturedroofO and the ends of the bed-plate D, of the aprons U, substantially asherein shown and described, whereby the space below the forward endoftheheater can be readily closed, as set forth.

5. In a heater for railway-cars, the bed-plate D, constructed withcurved grooves K, having inclines and recesses in their bottoms, andprovided with the double-inclined pivot-seat, and the collar I,substantially as herein shown and described.

6. In a heater for railway-cars, the stove-plate E, provided withcentral pivot, H, in combination with the bed-plate D and the collar I,substantially as herein shown, whereby the heater can be readily turnedand will be s'ecurely held, as set forth.

7. In a car, the combination, with the apertured roof 0 and the pivotedstove E, of the cross-bars O and the cover N, substantially asherein'shown and described, whereby the said cover is supported from andcarried around by and with the said stove, as set forth.
